Write a doc your agent builds from
Write a PRD, a spec, a playbook — your agent reads it over MCP and acts on it. The document is the brief, not a throwaway chat prompt you retype every session.
Collaborative markdown for teams and agentsThe shared context layer
The shared context layer
between your team and your agents.
Write a PRD and your agent builds from it. Point an agent at your codebase and get docs that stay current. Capture a playbook once and run it forever. Share any of it with a link.
Collaborative markdown · any MCP agent · share with a link
You re-explain everything to your agent every session. Your team re-finds what someone already wrote. Context is the tax you pay over and over — it should be written once and reused, by every teammate and every agent.
01How it works
Connect an agent. Brief it or let it build. Share what you make.
01
Connect your agent
One line of MCP. Any agent — Claude Code, Cursor, Codex — scoped to a space and revocable anytime.
02
Brief it, or let it build
Write a PRD it acts on, or point it at your codebase and get docs back — proposed as changes you review.
03
Share what you make
Invite your team into the space, or hand any document to the world with a public link that can expire.
02Why Hub
The one thing no chat window or AI sidebar can do
Point an agent at your codebase
Your agent reads the repo and writes the documentation — architecture, onboarding, support docs — and keeps it current as the code changes. The docs write themselves.
Hand any document out with a link
Invite colleagues into a space, or share a read-only public link with anyone — set an expiry and it closes itself. Beautiful markdown in, a shareable page out.
03For your agents
A first-class seat at the document
Point any MCP-capable agent at Hub with a scoped token. It reads the space guide, works in your docs, and proposes changes — every write version-guarded, so it refreshes and retries instead of overwriting a human.
- 01Connect your agent One line of MCP. Scoped to a document or a whole space, revocable anytime.
- 02Brief it, or let it build It reads the docs you wrote and acts on them — or writes new ones from your codebase, proposing changes you review.
- 03Share what you make Invite your team into the space, or hand any document to the world with a public link.
04Use cases
What teams build in Hub
Founders & small teams
Run the company from one brain
Strategy, GTM, decisions, hiring notes — all in one place. Your agents draft, tidy, and keep it current as things change.
team writes → agent tidies & summarizes → everyone builds on it
Engineering
Specs your coding agents actually read
RFCs, specs, and runbooks the team writes — and Claude Code reads before it builds, proposing updates back as reviewable suggestions.
team writes spec → agent reads → builds → reports back as suggestions
Solo builders
Your notes — now your agent’s too
A personal doc space your agents can actually use: they read your context, write back what they find, and nothing resets each session.
you write → agent works in your docs, not a throwaway chat
